IC4DESIGN is a Hiroshima-based illustration and design studio founded in 2006 by Japanese artist Hiro Kamigaki. The studio is known for its highly detailed, hand-drawn visual style, characterized by dense architectural environments, maze-like compositions, humorous background narratives, and bright, pop-artâÂÂinspired palettes.
Its best-known creation is the puzzle-book series Pierre the Maze Detective, which has sold more than one million copies and has been translated into over thirty languages. The studio has produced editorial, commercial, and narrative illustration for clients worldwide. Its work has been recognized by major illustration and design bodies, including American Illustration, the Society of Illustrators, and the Art Directors Club of New York (ADC).
IC4DESIGN traces its origins to 1998, when Hiroshima-born illustrator Hirofumi Kamigaki began working independently after deciding to pursue original illustration and creative autonomy. He had previously worked in a videogame design firm where he felt his work was derivative, and later worked at a design firm and an advertising agency. As a freelancer he began taking commissions from his apartment. His early years were marked by limited business knowledge and the difficulty of client outreach before widespread internet use, an experience he later described as formative in developing both persistence and a willingness to seek work proactively.
Kamigaki formally established IC4DESIGN in Hiroshima in 2006 as a small studio of illustrators working across editorial, commercial, and narrative projects. From the outset, the studio cultivated a collaborative production process involving shared sketching, iterative refinement, and multilayered hand-drawn detail, with some projects requiring years to complete. The group quickly became known for densely composed cityscapes and pop-artâÂÂinfluenced visual storytelling, attracting both domestic and international assignments.
IC4DESIGNâÂÂs early expansion into overseas markets was driven by KamigakiâÂÂs direct outreach: beginning in late 2008, he sent nearly one thousand emails and made about five hundred calls abroad in an effort to secure international representation. This effort landed him a New York agent and, in 2009, a breakthrough commission for the cover of The New York Times Magazine. Although the cover did not immediately raise the studioâÂÂs domestic profile, it increased international visibility, and established a foundation for further overseas work. Kamigaki later reflected that working from Hiroshima made pitching to Tokyo and New York feel equally accessible, and the success encouraged him to expand the studioâÂÂs global ambitions. Kamigaki and colleague Daisuke Matsubara also cited the 2010 Amtrak National Train Day poster as a formative milestone; selected for the U.S. competition without leaving Hiroshima.
By the mid-2010s, IC4DESIGN had gained global recognition and had completed notable commissions from multiple international clients. The release of Pierre the Maze Detective in 2014 further broadened the studioâÂÂs audience; the picture bookâÂÂs elaborate maze-based illustrations were widely exhibited, translated into multiple languages, and contributed to the studioâÂÂs growing international reputation. Subsequent volumes extended the seriesâ reach, with translations into more than 30 languages.
IC4DESIGNâÂÂs growing international presence in the late 2000s and 2010s paralleled its continued engagement with domestic clients. Its expanding overseas portfolio boosted commissions within JapanâÂÂparticularly from TokyoâÂÂand contributed to KamigakiâÂÂs acceptance into the Tokyo Illustrators Society, a form of âÂÂre-importedâ recognition that he has noted is especially valued by Japanese audiences. At the same time, the studioâÂÂs work became widely recognizable in its home city of Hiroshima, appearing across schools, real-estate firms, and other local businesses.
The studioâÂÂs style is defined by extremely dense, colorful, and whimsical cityscapes filled with humorous micro-narratives and hidden details. The deliberate and playful visual density and micro-narratives are designed to reward sustained viewing.
Their visual language draws clear inspiration from search-and-find traditions such as Where's Wally?, adapting the format into elaborate maze-based scenes that combine storytelling with puzzles. Kamigaki describes the studioâÂÂs signature extreme density as a strategic response to the intense competition he faced in overseas markets; producing images that viewers could study âÂÂfor minutes, not secondsâÂÂâÂÂa challenge given to him by The New York Times Magazine art director Arem Duplessisâ became a defining principle of IC4DESIGNâÂÂs aesthetic.
IC4DESIGNâÂÂs work is grounded in research-driven planning and a meticulous and collaborative production process. When designs are based on real locations, the studio develops illustrations through extensive reference gatheringâÂÂincluding photographs, maps, and studies of urban space and local detailâÂÂwhich inform both spatial composition and narrative layering. Projects typically progress through multiple stages, from rough sketches to detailed linework and final color, with some works requiring years of refinement; the production of the first volume of Pierre the Maze Detective, for example, took more than two years to complete.
Work is produced collaboratively, with team members contributing to planning, detailing, and execution.
IC4DESIGN is led by illustrator Hiro Kamigaki alongside longtime collaborator and art director Daisuke Matsubara, forming the core of a Hiroshima-based collective with a collaborative approach to illustration. Other team members include Yoko Sugi, Arisa Imamura, Masami Tatsugawa, Keiko Kamigaki, Liang Xiaoming, and later Yujiro Ayano. The studio has cultivated an internally cohesive, family-like working environment, where shared creativity and mutual support shape both daily routines and long-term projects. The team culture combines enjoyment, ambition, and openness to the world.
IC4DESIGN has built a portfolio of editorial and commercial illustration spanning Asia, the Americas, Europe, and the Middle East. The studio has produced magazine, campaign, and event imagery for clients including Mercedes-Benz, the NFL, Ford, Ogilvy Italy, Adobe Systems, Newsweek, Toyota, Google, Mazda, the Los Angeles Times, and institutions such as the Howard Hughes Medical Institute. Some notable projects include the following.
Closer to home, IC4DESIGN has completed a series of commissions closely tied to HiroshimaâÂÂs local identity. For MazdaâÂÂs 100th anniversary in 2020, Kamigaki created the âÂÂHiroshima Wakuwaku Coloring Sheet,â a dense illustration that integrates historic Mazda vehicles into a stylized cityscape featuring regional landmarks, local specialties, and playful visual exaggerations. In the same year, Hiroshima University commissioned âÂÂHiroshima University: Exploring Wonderland,â a panoramic depiction of its East Hiroshima campus that also incorporates the Kasumi and Higashi-Senda campuses, along with distant regional symbols such as the Atomic Bomb Dome and Itsukushima Shrine. Kamigaki also designed the universityâÂÂs phoenix symbol and mascot, Hiroty. Beyond institutional commissions, IC4DESIGNâÂÂs work has become a familiar presence in HiroshimaâÂÂs everyday environment, appearing in materials for schools, real-estate firms, vocational colleges, and local businesses. This includes the food e-commerce company Kakuichi Yokocho, whose collaboration with the studio was a local project that later received international recognition.
The studio has also undertaken projects for global media and technology platforms. IC4DESIGN contributed illustration assets for Google Hangouts emoji design and produced a special Oscars-day wrap cover for the Los Angeles Times, applying its character-dense visual approach to entertainment coverage. In collaboration with Adobe, Kamigaki developed designs for the 2023 Adobe Stock trend âÂÂRetro Active,â drawing on 1990s-inspired visual motifs consistent with themes explored in earlier work. For this project, the studio created complete illustrated scenes that were then separated into modular components for reuse within AdobeâÂÂs asset marketplace.
In addition to commercial and media-oriented work, IC4DESIGN has accepted commissions from religious and community institutions. During the COVID-19 pandemic, Kamigaki collaborated with Senkoji Temple in Onomichi to create and donate the âÂÂSenkoji Temple Illustration,â a detailed image intended to support community morale during a period of restricted travel and public gathering. The illustration incorporates references to local history, films, and events associated with Onomichi and the temple itself, reflecting the studioâÂÂs practice of embedding layered cultural detail within its compositions.
KamigakiâÂÂs most internationally recognized creation is the puzzle-book series Pierre the Maze Detective, developed with his team at IC4DESIGN. Each volume features sprawling double-page maze illustrations rendered as densely populated cityscapes, fantastical worlds, and interconnected visual narratives. The stories follow the young detective Pierre and his companion Carmen as they pursue the thief Mr. X, whose magical contraptions transform ordinary environments into labyrinths. Each scene includes a characteristic blend of figurative labyrinths, hidden objects, and whimsical details, including animals, ninjas, and futuristic elements.
Since the publication of the first volume Detective Pierre Solves the Case (Japan, 2014; international release 2015), the series has sold over a million copies and has been translated into over thirty languages. The franchise has expanded into multiple activity books, merchandise lines, and a video-game adaptation.
The first volume took over two years to complete. A Hiroshima exhibition presented the full workflow, which showed the project going from rough thumbnail sketches to final linework and coloring, highlighting the intensive work required for each scene.
The video-game adaptation, ' (2021), further expanded the seriesâ reach. Developed by French studio Darjeeling, the game animates environments directly based on artwork drawn by Kamigaki and IC4DESIGN. Players control Pierre as he searches for Mr. X across elaborate, hand-drawn scenes, turning the booksâ intricate worlds into explorable digital spaces. The game won multiple awards.
Kamigaki has stated his intention to publish five or six volumes during his lifetime.
Kamigaki also notes that the global popularity of the series increased his domestic visibility and contributed to what he calls the âÂÂthird phaseâ of his career. This is marked by frequent approaches from major international brands and an expansion of his creative goals beyond illustration into a wider range of creative projects, including exhibitions and narrative projects. Reflecting on the seriesâ worldwide reception, he expressed pride that a project born in Hiroshima now reaches audiences around the globe.
IC4DESIGN also featured in exhibitions in its home city of Hiroshima.
In May 2010, IC4DESIGN opened its first solo exhibition, "Line den City", at Gallery G in Hiroshima. The show featured a mix of commercial and personal works by Kamigaki, including his 2009 New York Times Magazine "Infrastructure" cover illustration and the artwork created for Amtrak's 2010 National Train Day campaign. Displayed as large-format, unframed prints for an informal presentation, the works encouraged visitors to explore the âÂÂgimmicksâ and hidden details characteristic of IC4DESIGNâÂÂs style. Kamigaki remarked that the attention brought a sense of pressure, but he hoped audiences would enjoy discovering the playfulness embedded in each piece.
A 2014 showcase of the production process behind Maze Detective Pierre presented the complete workflow behind the first book, from rough thumbnails to final linework and color. The exhibition displayed the intricately detailed illustrations on large panels and emphasized the two years and three months required to complete the volume. Kamigaki says the finished book feels like his own art collection.
In 2023, IC4DESIGN presented SofiaâÂÂs Labyrinth at the National GalleryâÂÂs Kvadrat 500 in Sofia. The exhibition introduced a maze-based illustrated city inspired by the Bulgarian capital, inviting visitorsâÂÂparticularly childrenâÂÂto navigate large-scale works combining KamigakiâÂÂs dense, labyrinthine style with locally inflected imagery. The illustrated scenes incorporated Bulgarian cultural references such as superheroes, kukeri (traditional folk figures associated with ritual performances intended to ward off evil and bring health and fertility), and rose pickers, and were designed around hidden objects, route-finding tasks, and small narrative challenges.
According to the National Gallery, the exhibition materials were developed through a combination of advance research and subsequent on-site study, resulting in both colorful and black-and-white versions of the illustrated city that blend fictionalized space with observed urban detail. During the exhibition period, the National Gallery also organized childrenâÂÂs educational programs connected to KamigakiâÂÂs work and the maze-based format.
IC4DESIGN and its founder, Hiro Kamigaki, have received international recognition across illustration, advertising, and design. Their breakthrough 2009 cover for The New York Times Magazine won an Art Directors Club of New York (ADC) 89 Silver Award and later became an American Society of Magazine Editors (ASME) Best Cover 2010 finalist, helping establish the studioâÂÂs global profile and leading to further overseas work. In 2021 Kamigaki served as a judge for the 100th Art Directors Club of New York (ADC) Awards.
Subsequent projects have garnered distinctions including a Cannes Lions Bronze, a One Show Silver plus additional Bronze and Merit awards, a D&AD Wood Pencil, and multiple Dubai Lynx Gold and Bronze prizes, notably for a UN Women workplace gender-equality campaign built around a hidden-woman search concept. The studio has also been selected by American Illustration and the Society of Illustrators, listed among the âÂÂ200 Best Illustrators Worldwide 09/10,â and featured in the books Illustration Now! Vol. 4 and Illustration Annual 52, underscoring its status within the global illustration community. In parallel, IC4DESIGN has earned distinctions in the 3ÃÂ3 International Illustration Awards, including Best of Show, Gold, and Merit honors.
